The PF0 pin of STM32F030R8T6 can't use interrupt function?
I use STM32cubeMX tool, generate interrupt function, compile and program successful in Keil V5. But this function doesn't work. How to solve the question?

Are we talking of EXTI interrupt source? Checklist:
- If PF0 is used other than GPIO, in CubeMX, EXTI and peripheral Alternate Function don't work as stacked pin. The direct HW register programming works fine.
- If other GPIO port 0 is used: In EXTI you can't have say PB0 and PF0 as interrupt source. Only one per pin number.
- Run the debugger, run the code, stop it and view the EXTI/GPIO registers manually. Modify manually the registers then let the code run to see if you find the culprit. Avoids lots of guessless recompile cycles.
